Here comes novel device equally harmful as traditional smoking, e-cigarettes

IANS  |  Sydney 

While we know about the harmful effects of traditional cigarettes and vaping, new heated devices are no less toxic to the human lung cells than ordinary smoke, said researchers, including one of Indian-origin.

The study has compared new heated devices, which heat solid instead of an e-liquid, with vaping and traditional cigarettes showing that all the three are toxic to the cells.

In addition, these newer can destroy lung tissue leading to such as chronic obstructive pulmonary disease, and pneumonia, and can increase the risk of developing

"is the leading cause of preventable death, and with the introduction of in the last decade, the trend of nicotine uptake is not going to slow down in the near future," said Pawan Sharma, a at the

"The latest addition in this emerging trend is the planned and vigorous introduction of They are commonly called next generation or We know very little about the health effects of these new devices, so we designed this research to compare them with and vaping," added Sharma.

For the study, researchers tested the effects of all three nicotine sources on two types of cells taken from the human airways: epithelial cells and smooth muscle cells.

In healthy lungs, epithelial cells act as the first line of defence to any foreign particles entering the airway while smooth muscle cells maintain the structure of the airway. However, can lead to difficulty in breathing primarily by hampering the normal functions of these cells.

The team exposed the cells to different concentrations of smoke, vapour and vapour from a heated tobacco device, and measured whether this was damaging to cells and whether it affected the cells' normal functions.

The findings, published in ERJ Open Research, showed that cigarette smoke and heated tobacco vapour were highly toxic to the cells both at lower and higher concentrations while vapour demonstrated toxicity mainly at higher concentrations.

Importantly, the review of the European Respiratory Society's Tobacco Control Committee's own data on these devices has shown that, in rats, there is evidence of lung inflammation, and there is no evidence of improvement in and function in smokers who switch to heated tobacco, said from the varsity.

"If the current trend continues, tobacco use will cause more than eight million deaths annually by 2030 around the world," noted Sharma.
